Hi Ken, normally the slider all the way to the right should generate a quite dense mesh... If you can post the model (or e-mail it to me at moi@moi3d.com if you wish to keep it private), I will take a look at it to see what might not be working right.

One other way to increase the density is to expand the meshing options dialog, which will give you a setting for "Divide larger than:" - you can enter a value here that will cause quads that are longer than this distance to be subdivided.
